Plot hole: The Disco Volante puts to sea and Bond comes aboard disguised as one of the divers. Largo tells the captain to set course to Miami Beach. After being exposed and captured within the underwater cave, Bond is eventually rescued by Leiter in a helicopter. Bond tells him that the Volante's course is Miami Beach and that the bombs are transferred to a wreck on Fowley Point. There is no mention of Fowley Point before - the wreck just serves as a location for the final underwater fight. (01:53:00)
Plot hole: Before the race starts, Sir Percy intends to sabotage some of the other fliers. He announces to Courtney that he had lured Dubois away by giving him the address of Courtney's daughter, but later, when the race starts, there is nothing wrong with Dubois' machine even though Sir Percy had the chance.
Plot hole: When Knut and Rolf are setting the bombs in the engine room of the Hydro ferry, they are interrupted by a German soldier who they quickly overpower and kill. Why don't the Germans then notice that this soldier is missing? The clocks attached to the bombs show the time around 01:35am when the soldier is killed yet the alarm still hasn't been raised when Rolf catches the ferry several hours later at 9am. This is far too long for any soldier to be on sentry duty without reporting in to the Guardroom. The Germans would have known that the soldier was on duty on the ferry and when he didn't report in then they would have searched the boat thoroughly and found the bombs. (01:51:30)
